Thermal Shock Resistance DOC

High-Performance Diesel Engine Ceramic Particulate Filter (CDPF/DOC)
This advanced ceramic particulate filter serves as a core component in diesel engine exhaust aftertreatment systems. Engineered with precision ceramic materials featuring a high-density honeycomb porous structure, it effectively captures and catalytically oxidizes carbon soot particles (PM) from exhaust gases. Essential for meeting China VI and higher emission standards while improving engine environmental performance.
Working Principle
Exhaust gases flow through the honeycomb ceramic substrate, where carbon soot particles are intercepted and deposited on the micropore surfaces. During system regeneration, accumulated particulate matter undergoes oxidation and cleaning at elevated temperatures through catalytic action, enabling periodic filter cleaning and maintaining sustained high-efficiency operation.
Core Technical Features
Feature Parameter/Description Technical Advantage
Structural Design Wall-flow honeycomb ceramic, cell density 200-300 CPSI Balances high filtration efficiency with low pressure drop
Filtration Mechanism Combination of depth filtration and surface filtration Capture efficiency >95% for nano-scale carbon soot particles
Material System Cordierite/SiC-based advanced engineering ceramic Combines high porosity, thermal resistance, and mechanical strength
Regeneration Compatibility Compatible with catalytic coatings (customizable DOC/SCR coating) Supports both passive and active regeneration, enhancing system durability
